Via Winter is Coming:
Jon Snow and Bran Stark
Tyrion Lannister and Catelyn Stark
The colour palette of the show is fantastic. Lots of browns and greys, absolutely perfect for the northern reaches of Westeros, where much of A Game of Thrones takes place. I’ll be interested to see how that palette changes as the show moves locations to King’s Landing, Dorne, The Dothraki Sea, The Iron Islands, etc… it should be a great opportunity to show the variety and depth of Martin’s world.
Several more photos, including Cersei Lannister, Danaerys Targaryen and Samwell Tarley, can be found on Entertainment Weekly’s Game of Thrones Photo Gallery.
